Central Japan Construction Consultant

What Central Japan Construction Consultant does

Central Japan Construction Consultant (中日本建設コンサルタント株式会社), also doing business as Nakanihon Engineering Consultants Co., Ltd., is a privately-held Japanese construction consulting firm founded in 1970 and headquartered in Nagoya, Aichi Prefecture. The company delivers planning, design, survey, and engineering consulting across the full spectrum of social infrastructure, organized around two principal technical domains: water environment (water supply, sewage, rivers and coastal, waste management) and transportation (roads, bridges, railroads), with additional practices in urban and regional planning, disaster prevention and BCP, public-private partnerships (PPP/PFI), municipal management consulting, and digital transformation (DX) services. The firm maintains an in-house R&D program that has produced proprietary technology such as the patented Electric Smart Meter-based Rainwater Infiltration Detection method for manhole pump stations, and participates in joint research and technical publication activity within the industry.

The company serves exclusively Japanese public-sector clients — national government agencies, prefectural governments, and municipal authorities — with revenue generated through government and municipal procurement contracts across twelve published service lines. Distribution is delivered through a direct enterprise field-sales motion anchored by the Nagoya headquarters and supported by Tokyo and Osaka regional branches that provide nationwide coverage. The firm has accumulated formal recognitions including Privacy Mark certification, repeated commendations from the Japan Sewerage Agency, MLIT PPP Agreement Partner designation through fiscal year ending June 2028, and multiple innovation awards from the Japan Water and Sewage Consultants Association.

The business operates with no disclosed revenue, headcount, or external funding, and is led by President and Representative Director Masashi Shomura (庄村昌明). There is no parent company, no institutional investor, and no subsidiaries identified. In August 2024 the company relocated its Nagoya headquarters to a new building featuring open-plan workspace and a free-address seating system while expanding its Tokyo and Osaka branches, consistent with an incrementally scaling mid-market Japanese engineering consultancy.
